Is this a correct opinion?? I am 15 and I want to make some money and this...

I am 15 and I want to make some money and this is my idea:
- budge to a thrift store and get some old "damaged" wood furniture
- Sand it down
- Stain it
- Sell it

I know how to use a sander and such because I took shop class within 8th grade. My dad said no because it would be too much work but all I enjoy been doing all summer is is sitting surrounded by front of the computer being bored and not making any money. Do you think this is a virtuous idea??
It would be easier to grasp free stuff from Craigs list, and once a month have a courtyard sale. Someone in our nieghborhood is doing this, and it must work, they've be at it for a couple of years now! if you really need it sure
Hmmm... 15 yr elderly doesn't want to sit in front of a computer all sunshine... wants to try to do something to earn a little money, gain for a moment experience. Sounds good to me! I say if you've get a little spare money and it's something you enjoy doing, who care if you make money on it or not? as your dad said, it's a lot of time, for possibly little return. but that said, it's biddable experience, and it's your time. so i say go for it. you computer will miss you.
Answers:    Are you doing this because you love it and you are itching for a creative outlet? Or are you doing it for money? I'm 33 and just in a minute learning that to really be fulfilled and successful, it's important to do what you do because you love it, not because there's money surrounded by it. If you have love, passion and talent, the money will follow.

It's great to hear how creative you are. In Chicago, within are people making good money doing only just what you propose to do. I will be publising an interview with local artist Ted Harris in the subsequent couple of weeks (on Strangeclosets.com, an interior design website). Ted does much what you propose to do and has made a very honest living.

Take care, and good luck.
Years ago, an accountant explained to me that near are always at least two things you can do near your money (or time). Invest in this or that.

It sounds like you are looking at a choice of where on earth to invest your wealth (your time and money). You could use your time in front of the computer and use your money for fun - or put it surrounded by the bank at 2%;
or you could invest your time and money (furniture purchase, stripper, sandpaper, electricity, etc) in this project.
In the first instance your network gain is the joy (or lack thereof) of spending time contained by front of the computer, and the joy of whatever you spent your money on, or the interest earn from parking it in the bank.
In the second scenario, you will own spent a lot of time working on a project (that may quickly become drudgery - or may be big in itself), and have your money tied up within your costs. To recoup the costs, you will need to find a purchaser for the furniture you've refinished, which will require more of your time. You may not find one likely to pay the price you want! In the worst case, you could be stuck near the finished piece, and out the investment of money and time.
The question is one only you can answer. If doing the project would administer you some intrinsic value -ie, you LIKE doing the work, so in doing it you perceive rewarded already, then your only cost is the money you hold to spend. Then that's your only risk. But if doing the work is a means single to greater financial return, be careful.
